MRM’s custom robotic tracking stone slingers are extremely beneficial when it comes to safety, speed and versatility.
We can place material 80 to 100 feet away at a rate of 9 tons per minute. We can precisely place sand, gravel, mulch, topsoil, and pea stone in any location. Our tracked machines work year-round in mud, grass yards, beaches, and parking lots. The rubber tracks can cross steep slopes and concrete curbs. Save time, money, and labor by having our stone slingers do the job.

Soil Erosion

MRM can install over 5,000 feet of ‎Filtrexx SiltSoxx per day, replacing silt fence with a more durable, longer lasting product in all sizes from 8″ diameter up to 36″ diameter. Also, we have 100% biodegradable material when you are working on slopes or in the middle of a muddy pipeline job. We can place filter sock just about anywhere.
